👋 HEY, IT'S RAJA

The last two Mondays have been about iOS 27, which is fine if you are running the beta and useless if you are not. Most of you are not. So today, something that works on your phone right now.

It is a battery setting. It has been sitting in Settings since last year, it is switched off by default, and almost nobody I ask has it on. If your phone is a year or two old and you are trying to nurse it through to whatever Apple announces next month, this is the free upgrade.

Leadership is asking: are we getting value from AI? Which tools are worth the spend? Where are we exposed? Right now, most teams have no idea.

Harmonic Security Usage Explorer changes that.

You get a complete picture of how your organization uses AI, automatically categorized into custom tasks and use cases.

You’ll see the projects being worked on, who’s using what tools, where AI investments are driving value, and where employees are engaging in risky behavior.

CIOs can rationalize spending and cut wasted licenses. CISOs can pinpoint where risk exists and neutralize it. AI committees can show exactly how their efforts are paying off.

See it in action

Not Low Power Mode. Something quieter that runs all the time and that you are not supposed to notice.

Adaptive Power watches how you actually use your phone and makes small adjustments on the days you are hammering it. It dims the screen very slightly, holds back background processes, and eases off performance where it thinks you will not feel it.

The word doing the work there is slightly. This is the opposite of Low Power Mode, which announces itself: yellow battery icon, mail stops fetching, everything gets a bit worse in exchange for hours. Adaptive Power is designed to be invisible. You are meant to reach the end of a heavy day with more left than you expected and no memory of having given anything up.

It also does not replace Low Power Mode. Low Power Mode still exists, and Adaptive Power will switch it on for you when you hit 20 percent. Think of Adaptive Power as the thing that happens all day and Low Power Mode as the thing that happens at the end of it.

That is the whole job. There is nothing to configure and nothing to maintain.

Two worth knowing.

It needs an iPhone 15 Pro or later. If you are on an older phone, this particular setting is not there, and I am aware of the irony that the battery feature aimed at squeezing more out of your day requires a relatively recent phone.

Second, it is genuinely subtle, which means you should not expect a dramatic before and after. If you were hoping to double your battery life, this is not that. It is a few percent at the end of a heavy day, reliably, for no effort and no visible cost. That is a good trade, but it is a quiet one.

📱 Platform: iPhone

📍 Where: Settings → Battery → Power Mode → Adaptive Power

🧪 Requires: iOS 26 or later, iPhone 15 Pro or newer

🔋 Works with: Low Power Mode, which it triggers at 20%

Four taps, and then you forget about it. That is the best kind of setting.

See you Wednesday, where I am looking at what happens when you let an AI read every message you have ever sent.

Keep it useful,
